Check Price ", "We actually own a real Dumble. ", (about the difference between the "JP Green" and "USA Clean") "JP has less gain and a much larger midrange potentiometer. The Friedman BE-100 amp was created after Dave Friedman had amassed years of experience working with mods on his client's Marshall plexis. In this case the voltage divider would be 26.7/317 = 0.084. This means the amps are biased somewhat cold to begin with and shift to very cold as soon as overdriven. However, I do think Friedman is overpriced for a factory assembled production line amp and is charging hand-wired, boutique prices. The OD-2 is not the best amp for those tones, I totally agree with you, but a Dumble or clone doesn't really do fast dampened power chords like the OD-2 will do either.

If you turn off Bright you're effectively clipping the bright cap. To simulate this increase the Negative Feedback. The only difference was I was using a GUI, not resistors and capacitors. ", "Our reference amp for the Silver Jubilee is actually not a Silver Jubilee. As you increase gain you want less bass into the distortion stages so the idea is you turn the bass down. For instance, Splawns are all built in house by 3 guys and are half the price on most models, but they are not sold in Guitar Center's throughout the country. This is the amp used on Dire Straits eponymous album. The bright cap varied over the years, supposedly depending on what was lying around in the shop. The breakup range/tones between is wide and dynamic and can respond to your playing dynamics, getting crunchier as you dig in and cleaner as you play lighter. literature. This particular amp is an early CBS Silverface but still using pre-CBS design and components. You can reduce this via either the PI Bias Excursion or Master Bias Excursion parameters. Or you can lower the Harmonics value which reduces the asymmetric distortion. Dave has been building, modding and repairing amplifiers for many of the world's biggest stars for the past 25 years.

Snapshot - try the M25 GB speakers, V30s, or a combination with the Friedman amps. Answer: Tube amps are undeniably a popular choice, especially for professional live performers. I don't mind who makes it as long the quality is just as good. The exposed "Bright Cap" is across the Drive pot, the X99 clean channel does not have one. Theyre loved by many professional musicians, and the brands website has a page dedicated to famous artists who use Friedman amps. ", "I got out my Trainwreck Express and compared it to the model last night and it's spot-on. Remember this was BEFORE anyone had even degooped or documented a Bluesmaster style circuit and the only thing Shad was building was his post count at AmpGarage asking about Dumble circuits.

To everyone else, we are in the golden age of guitar equipment. I'm happy to endorse that model because I put a lot of hours testing it and putting together a ton of technical information, fourier analysis graphs, frequency response graphs, schematics etc that would make validation of a mathematical model much easier. I think the default Master Volume value is a bit high so you may want to turn that down. Check the MV. ", (the new Herbert model in firmware 21 for the Axe-Fx III) "I like it a lot more than the old version of the amp. Ive had luck with the PCB board amps Ive owned. All nasty and spitty and full of "artifacts". ", "All the distortion comes from the power amp so the tone controls don't do much. That's a lot of feedback. I like it on, even with a bright guitar. ", "If it isn't Mid Gain then it's Harmonics. Friedman's designs are a bit odd in that he takes the feedback off the speaker jack rather than off a transformer tap. Dave Friedmans extensive knowledge and pursuit of tonal superiority inspired him to develop his own series of production amplifiers under the name Friedman Amplification. ", (about the Tech Note) "Applies to the Liverpool because the preamp is almost identical to the Express. I went through several before settling on this one as it was the best sounding by far. The Gear Page is the leading online community and marketplace for guitars, amps, pedals, effects and associated gear. The AFS100 models are based on the actual amp but I think my version of #34 sounds more like AFD. So many great choices out there and all are better than anything ever produced before. The Recto1 models are based on our Rev. In the actual amp the Treble control is re-purposed as a Negative Feedback control. The 1x12 Deluxe Tweed Mix cab is the IR. ", Earlier version of the amp with different component values, a little more aggressive than the regular model, "If you want more clarity in the low mids () reduce Negative Feedback.

Friedman Pink Taco 20W 1x10 Tube Guitar Combo Amp | Reverb Bogners use a log taper. As such there's a lot of bass going into the power amp. ", "18W Marshalls are kind of a bad design. never really had a use for them, but I'll leave that up to Dave. All the good bits without the bad stuff. Especially for the price in europe. It has the feedback of the 4-ohm tap whereas I've heard later versions have the feedback off the 8-ohm tap. A well designed PCB is the best way since it makes things more consistent and allows for shorter runs between the tubes and traces actually making it closer to point to point depending on the design. ", "The 50W version has a different input network than the 100W version for that channel. So I took the old Recto models and made them "Thordendal" models. Often called ' the best amplifiers ' in the online guitar world, Friedman amps have an excellent build quality, high and low inputs, awesome loop and master, and are fun to play, requiring minimal tweaking. The knob labeled Drive is the Master Volume. In other words that filter requires headroom to function properly, as does the presence control of any amp where it's a component of the feedback loop. This amp delivers midrange and tight bottom end, typically found in amps with a much higher wattage. ", "The Brit 800 #34 does a better Slash than the AFS100 IMO. Coupled with the right cab the emulated model does a good job of representing the basic tonal signature of the amp". I had it backwards in my earlier comments. This amp is perfect for metal and rock, both at home or on the road. It was by studying that and a really nice JCM-800 that I finally figured out the secret to cathode follower. So it's a high-gain Dumble. ", "Note that the knobs on '5' on the Axe-Fx correspond to '6' on an SLO because they go to 11. ", "As with the real amp I dial in quite a bit of Hi-Cut. AC-30's have kind of crappy OTs. When it came time for Dave to design his own line of pedal boards, everything a touring or home guitar player actually needs was meticulously thought out and addressed. The other thing that helps the tone is the 220K plate resistor on the last triode. Some distortion pedals also do this. Whether you require it for your profession, passion, or hobby, youve purchased it to enjoy and so protecting it from the point of purchase can be invaluable. If an amp model is "G3'd" it is deadly accurate. It's worse on lower notes because lower notes have more energy and charge the cap more. ", "It does classic rock extremely well and has one of the best clean channels I've ever designed. The models are based on the higher gain input (the "1" input). ", "JCM800s sound better with a hot bias IMO. ", "So-called Class-A amps (like the AC30) don't actually exhibit much power supply sag because, well, they're Class-A (or nearly). Too much IMO. "I begrudgingly dragged the amp out of storage today (as it weighs a metric ton) and repeated the measurements and did some A/B tests. The gain staging, overdrive voicing and output stage are night and day to ANYTHING Mesa, any owner of the real amp would attest to that. Mesa always says things like "sounds the same as a IIC+" but the circuits are different and, probably most important, the knob tapers are completely different. You can also play this amp silently, meaning you can use the amp without having to have it connected to a speaker cabinet so its great for practice and rehearsals. ", "There's a 0.68uF cap on the second triode. to get the tone to match. The Atomica is essentially a slightly modified JCM800 with a Jose-style zener clipper. In the past, having Friedman build or modify your amp required a certain level of notoriety, but now his sonic wizardry is available to everyday players. Using the 300B tube type should get you pretty close. Clean channel, hot rod Marshall channel, and a super hot rod Marshall channel. Its pretty forgiving on speakers compared with some models. ", "The reason they clean up when you back off the volume is because the OT is so overmatched. ", "Reference amp is a Slash AFD100 Signature Special Collector's Edition #76. The model uses average. As you increase the Master the highs get muffled. Guitar tube amp design was nascent in the 60s and 70s and designers didn't fully understand the impact of overdriving tubes. The taper is not.

If you do this on a Bogner it's like turning the treble way down on a Marshall. Detroit is a city with a rich history, not exclusively, but especially, when it comes to music. Our model is based on the Canadian one. ", "Brootalz uses the Engl Savage presence network which reduces negative feedback as the control is turned down causing an increase in volume. This is modeled by the Treble control in the Axe-Fx II. As was indicated in the release notes you can dial out this behavior by decreasing the PI Bias Shift. If a knob isn't present in the Authentic menu then it may not do anything in the Ideal menu. Bogners are too dark. The only unique thing I've encountered in all my tests is the function of the Presence Shift pull on the JP2C. Since the power amp has similarities to a Marshall perhaps Eddie wanted the presence control to behave like his old Marshalls. Kind of like how their are lots of guitars made in Korea at one factory for a lot of different brands. ", "The Buttery model was REPLACED by a Budda Twinmaster model. When you crank them up it smooths out. To simulate the Boost switch use the Boost switch in the amp block as it has the same amount of gain. Experiment with different values of Negative Feedback. In this case you would then double the feedback on top of the 3.3 so 9.9 or so. Many of the amp models are featured in Factory presets. As you increase the MV the source resistance increases which decreases both of these things. ", "Interpol "The Rover" (Prod. Channel 3 on a Mark V is virtually identical to the Mark IV Lead channel except for the pot tapers. Famed for his exacting and innovative amp building, modding, and repairing, Friedman finally branched out and developed his own line of amplifiers. Mine is an '81 and doesn't have cascaded gain stages. Another technique is to put a capacitor across the second-to-last triode stage.

Screwed around a little with the tube bias points until it had the right balance of harmonics and called it a day. The input gain network is different and the coupling cap after the second triode stage is a different value. There is no NFB in the Modern Red mode so the Depth knob won't do anything. Dave Friedman has brought together American and British tones and packaged it up beautifully in the Buxom Betty. We already know Dave Friedman's modded take on Marshall tones results in some incredible rock toneage so bringing it to more people with the latest Pink Taco Mk II and Little Sister 20-watt tube amps is great news.

To derive from Classic American Clean to Classic British Crunch all you need to do is turn up the volume knob its that simple and the results are incredible. Why they chose a log taper in the 5150 is a mystery. The tubes are biased hot so when one tube is conducting more the other is conducting less and the net supply current doesn't change much. You can simulate this using the Input Trim knob. Some amps have a second drive control, typically called an Overdrive, located further downstream which allows you to balance the pre- and post distortion. Since the gain pot and bright cap interact this makes a HUGE difference. Both the hand-wired and PCB stuff. J. ", "IMO the designs are poor because wait for it they exhibit a papery buzz.
